Hannoa klaineana

Shrub to high forest tree; branchlets glabrous. Leaves alternate, imparipinnate, 2–5(–8)-jugate, 8–40(–55) cm long; leaflets opposite or subopposite, drying greenish brown above, paler beneath, terminal and basal leaflets usually smaller than the other laterals; leaflet-blade narrowly to broadly elliptic or obovate, 2–20 cm long, 1–8 cm wide, emarginate or rounded to shortly acuminate at the apex, rounded to cuneate, often oblique at the base, coriaceous, glabrous, often with pitted glands on the upper surface, nervation indistinct, impressed, margin entire, sometimes slightly wavy; petiolule 1–40 mm, very variable within the species but fairly constant for each specimen; rachis terete. Flowers in terminal and axillary thyrses, inflorescence branches pubescent to glabrous; pedicels 1.5–10 mm long. Calyx 2–4.5 mm long, 2–5-lobed (often fissuring irregul­arly to give variable number of lobes), glabrous inside, glabrous to puberulent outside. Petals 5, imbricate, narrowly ovate to oblong, 3–7 mm long, 1–2.5 mm wide, subacute, puberulent outside, puberulent to pilose inside. Stamens from 1.5–3 mm long in female or bisexual flowers, up to 7 mm in male flowers; appendage 1/2–2/3 as long as the whole stamen, pilose with short free tip; anther ± 1 mm long, broadly elliptic. Disc annular to sub-cylindrical, 0.2–1.5 mm thick, 1.2–2.5 mm in diameter, furrows on outside to accommodate stamens, partially enveloping the ovary in male flowers. Ovary 0.8–1.5 mm long in female or bisexual flowers, reduced in male flowers; carpels 5, free, each containing 1 ovule; styles 0.3–2 mm long, cohering. Fruits drupaceous mericarps 1–3(–4) together on fruiting pedicels, ± ellipsoidal to oblong, apex obtusely pointed, base rounded, often slightly bicarinate and somewhat flattened, 15–35 mm long, 9–20 mm wide. Seed 1 per mericarp. Fig. 4.
